THREAD-GUIDE FOR SPINNING-FRAMES.

Specification of Letters Patent.

Patented May *7, 1912.

Application fiIedJune 9, 1911. Serial No. 632,132.

To all whom it may concern:

Be it known that I, VVILLIAM O. Bos- WORTH, a citizen of the United States, residing at Northbridge, in the county of Vorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Thread-Guides for Spinning-Frames, of which the following is a specification, accompanied by drawings forming a part of the same.

My invention relates to-an improved construction for supporting the thread guides of a spinning or twisting machine, and especially to means for easily temporarily displacing an individual thread guide so that the corresponding spindle may be dotted. The ordinary method now in use consists in holding the individual thread guides in hinged finger boards capable of being raised or turned back on their hinged connections. By my construction a much simpler method is employed and the same result accomplished by moving the thread guides to either side, and my construction further enables the various thread guides when in position to be securely held in proper alinement with the spindles and to project from the plate or finger head board at exactly a right angle thereto. These objects, among others, I accomplish by means of the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the drawings, Figure 1 is a top view of a portion of the plate hinged to the frame of the machine and supporting the thread. guides. Fig. 2 is a bottom view of one of the thread guides. Fig. 3 is a sectional View of Fig. 1 on the broken line 3-3. Fig. 4 is a bottom view of a portion of the plate supporting the thread guides, showing the grooves in which the shanks of the thread guides are held. Fig. 5 is a front view of Fig. 4.

Similar reference characters refer to similar parts in the different figures.

Referring to the drawings, 1 denotes a portion of the frame of the spinning or twisting machine, and hinged thereto in the usual manner is a metal plate or finger head board 2 having at its rear side a flange 3, connected by hinges, one of which is denoted at 4, with a corresponding flange 5 on the frame 1 to normally hold said plate or finger head board in a horizontal position. At intervals on the under side of the plate 2- to correspond with the spindles below, and at right angles to the front and rear edges of said plate, are shallow grooves 6, and 111 the line of said grooves are holes 7 and 8. In the forward hole 7 is loosely fitted a rotatable cylindrical head 9, pro vlded with a hole through which the shank 10 of a thread guide 11 passes. Said shank is firmly held in place by a set screw 12. By this construction the shank 10 is capable of being longitudinally adjusted.

Toward its lower end the rotatable head 9 1s provided with a neck 13 forming a shoulder 13 against which a bent spring It bears, having a hole through which the neck 13 of the head 9 passes. The rear end of the spring lt is attached to the plate 2 by a bolt 15 and nut 16 fitting the polygonal hole 8. The spring 14 supports the head 9 and forces it upward to press the shank 10 of the thread guide into the groove 6.

When it is desired to doif an individual spindle, its thread guide is moved to one side, as shown by the broken lines 17 Fig. 1, cansmg the shank 10 to be moved out of its groove against the tension of the spring 14.

I claim,

1. In a thread guiding means for a spinning frame, a supporting plate provided. with a transverse groove, a rotatable head held in said plate, a thread guide held in said head, and yielding means for holding the shank of said thread guide in said groove when said guide is in operative positron.

2. In a thread guiding means for a spinning frame, a supporting plate for a thread guide, a rotatable head held in said plate, a thread guide held in said head and provided with a straight shank, a groove or recess in said plate to receive the shank of said thread guide, and a spring with its tension applied to said rotatable head to press said shank into said groove.

3. The combination of a supporting plate, having an opening for a rotatable head, and a single transverse groove in diametrioal alinement with said opening, a rotatable head held in said opening and capable of longitudinal movement therein, a thread guide having its shank held from longitudinal movement in said head, and a spring with its tension applied to said head to hold the shank of said thread guide against said supporting plate.

4. In a spinning frame, the combination of a thread guide supporting plate having a hinged connection with the framework of the machine and provided with a series of transverse grooves, a series of thread guides having their shanks resting in said grooves when in operative position, and means for applying a yielding pressure to said shanks to press them against the supporting plate.

5. The combination with a hinged supporting plate, of a rotatable head journaled in said plate and capable of longitudinal movement, means for imparting a yielding pressure to said head to hold it from longitudinal movement, a thread guide held in said head, and means on said supporting plate for engaging said thread guide to hold it in a predetermined position.

6. The combination with a supporting plate having a circular opening and a groove in diametrical alinement with said i opening, of a rotatable head held in said opening and capable of a longitudinal movement therein, a thread guide with its shank held from longitudinal movement in a transverse hole through said head and arranged to bear against said supporting plate, a spring applied to said head to press said shank against said plate, said thread guide being capable of being moved into and out of engagement with said groove against the tension of said spring.

Dated this third day of June, 1911.
